During the last few years the presence of high arsenic (As) concentrations in ground water has been of major concern both internationally and in Sweden. Much evidence has been reported about toxic effects caused by arsenic. The carcinogenic effects and the possibility to measure the toxic impacts at low concentrations made the World Health Organisation (WHO) to reduce the guideline value from 50 to 10 ?g l-1 in 1993. In Sweden the corresponding reduction was implemented in 2003. Several surveys in Sweden have shown that high arsenic concentrations may occur in ground water.

The farming system is the basis of human existence through its production of provisions for man. By a continuous exchange of information, energy and material, between the ecosystems and the social systems, the farming system becomes an emergent property. The system's own properties, in the sense of farming methods, circulations and institutions, evolve through an adaptive process. Understanding this process and constantly learn from it, is the starting point for creating a sustainable development within farming systems. Thus, future farming system has to develop strategies that produce food provisions while at the same time takes into consideration the ecosystem's resilience and its integrity, but which also enables an ethical discussion. The institutions within the farming system are understood as links between the ecosystems and the social systems.

Orust Kommun står inför arbetet med att förnya och utveckla ett industriområde vid hamnen i Mollösund. Målet är att bevara kulturarvet i den lilla fiskebyn samtidigt som man vill satsa på ett levande samhälle, den viktiga turistnäringen samt tillfredställa många målgrupper. Rapportens syfte är att föra en diskussion och därmed bidra med ett underlag till Orusts kommuns arbete och beslut för förändring av industritomten belägen i Mollösunds hamn. Detta genomförs genom en fallstudie där ett antal befintliga områden analyseras, vilka alla är relevanta för industriområdet i Mollösund. Diskussionen skall belysa olika typer av verksamheter som kan inhysas på industritomten och analysera vilka som är mer eller mindre lämpliga.Genom en kritiskt granskad litteraturstudie inhämtades bakgrundsinformation om Mollösund och turism för att förstå bakgrunden till Mollösunds identitet.

In Sweden today so-called "prescribed nature conservation burning" is performed due to the change in silvicultural law, certification and an increased knowledge regarding the field of fire in the forest landscape. The aim is to re-create structures and qualities made by the fire regimes of the past, though on a much smaller geographical scale. The structures and qualities to be re-created are for example broad leaf stands, trees with large diameter, heterogeneous stands regarding variables such as age and diameter. If we increase our knowledge of the constitution of forests characterized by fire, then we will be able to set goals for what achievements to reach both on landscape scale and stand scale. The aim of this paper is to try to describe how a stand from the past was composed regarding mainly the spatial arrangement and compare it with the stand of today in the same place. This to be done by using relict material, that is stumps and dead standing trees.
